Test D: A Single Power Window Is Inoperative - Passenger Rear

PINPOINT TEST D: A SINGLE POWER WINDOW IS INOPERATIVE - PASSENGER REAR

Normal Operation
Voltage is supplied to the left rear and right rear power windows from the driver window control switch through circuit 170 (RD/LB). If the driver window control switch is in the LOCK position, the circuit is open and the windows do not operate from their respective window control switches.

NOTE: Police vehicles have additional rear window disable in line connector between the driver window control switch and the RH and LH rear window control switches on circuit 170 (RD/LB). Make sure the window(s) are in the operational position when making measurements.

LH Rear
When operating the LH rear window in the down direction, ground is provided from the driver window control switch through circuit 317 (GY/OG). Voltage is supplied to the LH rear window motor through circuit 334 (RD/YE) and ground through circuit 333 (YE/RD).

When operating the LH rear window in the up direction, ground is provided from the driver window control switch through circuit 316 (YE/LB). Voltage is supplied to the LH rear window motor through circuit 333 (YE/RD) and ground through circuit 334 (RD/YE).

When the LH rear power window is operated in the down direction from the driver window control switch, voltage is sent to LH rear window control switch through circuit 316 (YE/LB), which transfers power to the LH rear window motor through circuit 334 (RD/YE). Ground is provided to the LH rear window control switch through circuit 317 (GY/OG), which transfers ground to the LH rear window motor through circuit 333 (YE/RD). When the LH rear window is operated in the up direction from the driver window control switch, voltage is sent to the LH rear window control switch through circuit 317 (GY/OG), which transfers power to the LH rear window motor through circuit 333 (YE/RD). Ground is provided to the LH rear window switch through circuit 316 (YE/LB), which transfers ground to the LH rear window motor through circuit 334 (RD/YE).

RH Rear
When operating the RH rear window in the down direction, ground is provided from the driver window control switch through circuit 319 (YE/BK). Voltage is supplied to the right rear window motor through circuit 334 (RD/YE) and ground through circuit 333 (YE/RD).

When operating the right rear window in the up direction, ground is provided from the driver window control switch through circuit 320 (RD/BK). Voltage is supplied to the right rear window motor through circuit 333 (YE/RD) and ground through circuit 334 (RD/YE).

When the right rear power window is operated in the down direction from the driver window control switch, voltage is sent to right rear window control switch through circuit 320 (RD/BK), which transfers power to the right rear window motor through circuit 334 (RD/YE). Ground is provided to the right rear window control switch through circuit 319 (YE/BK), which transfers ground to the right rear window motor through circuit 333 (YE/RD). When the right rear window is operated in the up direction from the driver window control switch, voltage is sent to the right rear window control switch through circuit 319 (YE/BK), which transfers power to the right rear window motor through circuit 333 (YE/RD). Ground is provided to the right rear window switch through circuit 320 (RD/BK), which transfers ground to the right rear window motor through circuit 334 (RD/YE).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH rear passenger window control switch
- RH rear passenger window control switch
- Driver window control switch
- LH rear window regulator motor
- RH rear window regulator motor
